Ask a Question: The scientific method starts when আপনি ask a প্রশ্ন about something that আপনি observe: How, What, When, Who, Which, Why, অথবা Where?
And, in order for the scientific method to answer the প্রশ্ন it must be about something that আপনি can measure, preferably with a number.
Do Background Research: Rather than starting from scratch in putting together a plan for answering your question, আপনি want to be a savvy scientist using লাইব্রেরি and Internet research to help আপনি find the best way to do things and insure that আপনি don't repeat mistakes from the past.
Construct a Hypothesis: A hypothesis is an educated guess about how things work: "If _____[I do this] _____, then _____[this]_____ will happen." আপনি must state your hypothesis in a way that আপনি can easily measure, and of course, your hypothesis should be constructed in a way to help আপনি answer your original question.
Test Your Hypothesis দ্বারা Doing an Experiment: Your experiment tests whether your hypothesis is true অথবা false. It is important for your experiment to be a fair test. আপনি conduct a fair test দ্বারা making sure that আপনি change only one factor at a time while keeping all other conditions the same. আপনি should also repeat your experiments several times to make sure that the first results weren't just an accident.
Analyze Your Data and Draw a Conclusion: Once your experiment is complete, আপনি collect your measurements and analyze them to see if your hypothesis is true অথবা false. Scientists often find that their hypothesis was false, and in such cases they will construct a new hypothesis starting the entire process of the scientific method over again. Even if they find that their hypothesis was true, they may want to test it again in a new way.
Communicate Your Results: To complete your science fair project আপনি will communicate your results to others in a final প্রতিবেদন and/or a display board. Professional scientists do almost exactly the same thing দ্বারা publishing their final প্রতিবেদন in a scientific journal অথবা দ্বারা presenting their results on a poster at a scientific meeting.
